The security manager 352 may provide various security functions utilized for system security or user authentication. According to an embodiment, when an electronic device (for example, the electronic device 101) includes a phone function, the middleware 330 may further include a telephony manager for managing a voice or video call function of the electronic device.

The middleware 330 may include a middleware module for forming a combination of various functions of the above-mentioned components. The middleware 330 may provide a module specialized for each type of OS to provide differentiated functions. Additionally, the middleware 330 may delete part of existing components or add new components dynamically.

The API 360 (for example, the API 145), for example, as a set of API programming functions, may be provided as another configuration according to OS. For example, in the case of android or iOS, one API set may be provided for each platform and in the case Tizen, at least two API sets may be provided for each platform.

The application 370 (for example, the application program 147), for example, may include at least one application for providing functions such as a home 371, a dialer 372, an SMS/MMS 373, an instant message 374, a browser 375, a camera 376, an alarm 377, a contact 378, a voice dial 379, an e-mail 380, a calendar 381, a media player 382, an album 383, a clock 384, health care (for example, measure an exercise amount or blood sugar), or environmental information provision (for example, provide air pressure, humidity, or temperature information).

According to an embodiment, the application 370 may include an application (hereinafter referred to as “information exchange application”) for supporting information exchange between the electronic device (for example, the electronic device 101) and an external electronic device (for example, the electronic device 102 or 104). The information exchange application, for example, may include a notification relay application for relaying specific information to the external device or a device management application for managing the external electronic device.

For example, the notification relay application may have a function for relaying to an external electronic device (for example, the electronic device 102 or 104) notification information occurring from another application (for example, an SMS/MMS application, an e-mail application, a health care application, or an environmental information application) of the electronic device. Additionally, the notification relay application may receive notification information from an external electronic device and may then provide the received notification information to a user. The device management application, for example, may manage (for example, install, delete, or update) at least one function (turn-on/turn off of the external electronic device itself (or some components) or the brightness (or resolution) adjustment of a display) of an external electronic device (for example, the electronic device 104) communicating with the electronic device, an application operating in the external electronic device, or a service (for example, call service or message service) provided from the external device.

According to an embodiment, the application 370 may include a specified application (for example, a health care application) according to the property (for example, as the property of an electronic device, when the type of the electronic device is a mobile medical device) of the external electronic device (for example, the electronic device 102 or 104).

FIG. 4A is a block diagram of a call forwarding system according to various embodiments of the present disclosure.

Referring to FIG. 4A, the call forwarding system may include a first electronic device 410, a second electronic device 420, an electronic device management server 430, a communication carrier server 440, and a network 450. However, such the call forwarding system of FIG. 4A is just one embodiment of the present disclosure and thus the present disclosure is not interpreted as limited through FIG. 4A. For example, although the electronic device management server 430 is illustrated as an independent device, it may be included in the communication carrier server 440 that is a server managed by a carrier (for example, KT, SKT, LGT, Verizon, and AT&T, etc.). The carrier server 440 is now to be referred to as a communication carrier 440.

As described above, the first electronic device 410 and the second electronic device 420 may be one of various kinds of electronic devices having a communication function. For example, the first electronic device 410 may be a handheld device such as a smartphone or a smart pad, and the second electronic device 420 may be a wearable device such as a smart watch or smart glasses. Hereinafter, it will be assumed that the first electronic device 410 is a smartphone handheld device and the second electronic device 420 is a smart watch wearable device.

The first electronic device 410 and the second electronic device 420 may be utilized by the same user. For example, the first electronic device 410 and the second electronic device 420 may both be owned by one user. In this case, an independent phone number may be assigned to each of the first electronic device 410 and the second electronic device 420. Accordingly, the first electronic device 410 and the second electronic device 420 may execute a call with or exchange a message with another electronic device independently. A phone number at this point is assigned from the carrier 440 and may be different from an IP address utilized for transmitting and receiving IP-based Voice over Internet Protocol (VOIP) or IP-based instant message, electronic device identifier ID, or user identifier ID of an electronic device.

The first electronic device 410 and the second electronic device 420 may be used by being mutually paired with one another. The pairing method may include various methods such as Bluetooth (BT), Near Field communication (NFC), wireless fidelity (WiFi), and WiFi direct. Hereinafter, pairing using BT will be described as an example.

The first electronic device 410 and the second electronic device 420 may have mutual complementary functions when they are paired and utilized together. A user may pair the first electronic device 410 and the second electronic device 420 in a normal situation and then use them.

According to various embodiments of the present disclosure, since the first electronic device 410 and the second electronic device 420 are owned by the same user, when the user leaves their home (for example), the user may carry only one electronic device (for example, the second electronic device 420) of the first electronic device 410 and the second electronic device 420. As described above, since an independent phone number is assigned to each of the first electronic device 410 and the second electronic device 420, each may process an outgoing call or an incoming call, and transmit and/or receive a message independently. However, in this case, a user cannot check calls and/or messages received by the first electronic device 410 when leaving the home, as the first electronic device 410 was left in the house as a reception device.

According to an embodiment of the present disclosure, the first electronic device 410 left in the house may be set to forward calls and/or messages received by the first electronic device 410 to the second electronic device 420, which is carried by a user. However, in this case, when the first electronic device 410 is not connected to a free network (such as WiFi), but rather to cellular data of 3G or 4G, excessive charges may be added to the user's monthly charges.

Accordingly, according to various embodiments of the present disclosure, when a specified condition is satisfied, the first electronic device 410 or the second electronic device 420 may request call forwarding from the carrier 440 in order to allow the second electronic device 420 to receive a call and/or message targeting the first electronic device 410 as a reception device.

For example, when a BT pairing between the first electronic device 410 and the second electronic device 420 is released, the first electronic device 410 or the second electronic device 420 may detect the BT pairing release and may request the start of call forwarding service from the carrier 440.

According to another embodiment of the present disclosure, when a BT pairing between the first electronic device 410 and the second electronic device 420 is released, the second electronic device 420 may transmit a call forwarding request to the first electronic device 410 and the first electronic device 410 may transmit the call forwarding request to the carrier 440, thereby requesting the start of call forwarding service.

The second electronic device 420 may, in some embodiments, directly transmit the call forwarding request to the first electronic device 410, but in other embodiments, the second electronic device 420 may first establish a communication channel with the first electronic device 410 through the electronic device management server 430 and then, the second electronic device 420 may transmit the call forwarding request to the first electronic device 410 through the established communication channel.

The electronic device management server 430 may establish a session between the first electronic device 410 and the second electronic device 420. For example, the electronic device management server 430 may receive a request for connection to the second electronic device 420 from the first electronic device 410 or may receive a request for connection to the first electronic device 410 from the second electronic device 420 to establish the session. The first electronic device 410 and the second electronic device 420 may exchange (or collect) information (for example, each identification information and phone number, etc.) for each other during pairing. Accordingly, when the pairing is released, the first electronic device 410 or the second electronic device 420 may request the establishment of the session from the electronic device management server 430 by using the exchanged (or collected) information.

The electronic device management server 430 may check (e.g., detect) a communication state of the first electronic device 410 and/or the second electronic device 420. For example, the electronic device management server 430 may check the communication state of the first electronic device 410 and/or the second electronic device 420 by using a network ping and checking of the communication state may be performed repeatedly by a specified time unit. For example, when the network ping is received at a faster period than a predetermined period, the electronic device management server 430 may determine that the first electronic device 410 and/or the second electronic device 420 are/is in a communicable state. Unlike this, when the network ping is received at a slower period than a predetermined period, the electronic device management server 430 may determine that the first electronic device 410 and/or the second electronic device 420 are/is in a communication disabled state.

If it is determined that the first electronic device 410 is in a communication disabled state, the electronic device management server 430 may notify the second electronic device 420 that the first electronic device 410 is in a communication disabled state. Similarly, if it is determined that the second electronic device 420 is in a communication disabled state, the electronic device management server 430 may notify the first electronic device 410 that the second electronic device 420 is in a communication disabled state. In this case, the first electronic device 410 may request the release of a call forwarding service set the second electronic device 420 as a target device from the carrier 440.

The electronic device management server 430 may manage each identification information on the first electronic device 410 and/or the second electronic device 420 by matching each identification information with the first electronic device 410 and/or the second electronic device 420 in order for the management of the first electronic device 410 and/or the second electronic device 420. The identification information may be the unique identifier ID of an electronic device, a phone number that the carrier 440 assigns, ICCID information, or IMSI information.

According to various embodiments of the present disclosure, the electronic device management server 430 may synchronize the first electronic device 410 with the second electronic device 420 on a call, message, and event history of each of the first electronic device 410 and the second electronic device 420.

The carrier 440 represents a server managed by a communication carrier and may receive, from the first electronic device 410 or the second electronic device 420, the request of call forwarding (for example, transmits, to the second electronic device 420, a call and/or message that targets the first electronic device 410 as a reception device) that targets the second electronic device 420 as a target device, and may perform the call forwarding in response to this.

The carrier 440 may use information on the first electronic device 410 and the second electronic device 420 in order to perform the call forwarding. For example, the carrier 440 may read information of a SIM card equipped in the first electronic device 410 and the second electronic device 420. According to various embodiments of the present disclosure, the SIM card may include identification information such as Mobile Country Code (MCC), Mobile Network Code (MNC), and Group Identifier (GID). Herein, the MCC may be used to identify the country where the electronic device is used and the MNC may be used to identify a specific network in the identified country. Additionally, the GID may be used to identify the group of a specific electronic device among electronic devices having the same MCC and MNC. Therefore, the carrier 440 may determine whether the first electronic device 410 and the second electronic device 420 are electronic devices that are call forwarding targets for each other by using at least one of the MCC, MNC, and GID included in the SIM card of each of the first electronic device 410 and the second electronic device 420. For example, when it is determined that the first electronic device 410 and the second electronic device 420 are matched to one user account, the carrier 440 may provide call forwarding service.

Similarly, when the carrier 440 receives a release request for the call forwarding service that is set the second electronic device 420 as a target device, from the first electronic device 410 or the second electronic device 420, in response to this, the carrier 440 may release the set call forwarding with respect to the first electronic device 410 and the second electronic device 420.

In the above, it is assumed that an independent phone number is assigned to each of the first electronic device 410 and the second electronic device 420. Hereinafter, as various embodiments of the present disclosure, the call forwarding system will be described by using the case that the first electronic device 410 and the second electronic device 420 has one common phone number as one example. For example, the first electronic device 410 and the second electronic device 420 may have a relationship with different IMSI information but the same mobile station international ISDN number (MSISDN).

The carrier 440 may manage the first electronic device 410 and the second electronic device 420 with a multi-SIM concept using a main-SIM and a sub-SIM. The main-SIM allows an electronic device to perform data communication and perform the transmission/reception of a text message and the incoming/outgoing of a call. On the other hand, the sub-SIM is limited to at least part of functions of the main-SIM and may allow an electronic device to perform only data communication, only the incoming/outgoing of a call, or only the transmission/reception of a text message. However, since a function for supporting the main-SIM and the sub-SIM may vary according to each carrier 440, various embodiments of the present disclosure are not limited to the described embodiment. Hereinafter, it will be described that the sub-SIM performs only a data communication function.

It is assumed that the first electronic device 410 uses the main-SIM and the second electronic device 420 uses the sub-SIM. The main-SIM and the sub-SIM are not a role-divided physical configuration and are determined according to the property that the carrier 440 assigns. Due to the above-mentioned pairing release between the first electronic device 410 and the second electronic device 420, the carrier 440 may receive a signal for requesting call forwarding from the first electronic device 410 or the second electronic device 420. In this case, the carrier 440 may change the main-SIM property assigned to the first electronic device 410 into the sub-SIM property and may change the sub-SIM property assigned to the second electronic device 420 into the main-SIM property. With this, an incoming call received from the outside may be transmitted to the second electronic device 420 instead of the first electronic device 410. Alternatively, the carrier 440 may temporarily assign the role of the main-SIM to the sub-SIM property assigned to the second electronic device 420.

The first electronic device 410, the second electronic device 420, the electronic device management server 430, and the carrier 440 in the call forwarding system may be connected to each other through the network 450. At this point, the network 450 means an information exchange available connection structure between each of mutual nodes such as terminals and servers and may include various kinds of communication methods supported by the communication interface 170 of FIG. 1 and/or the communication module 220 of FIG. 2.

Hereinafter, the first electronic device 410 and the second electronic device 420 included in the call forwarding system of FIG. 4A will be described in more detail.

FIG. 4B is a block diagram of the second electronic device 420 according to various embodiments of the present disclosure. Referring to FIG. 4B, the second electronic device 420 may include a first communication module 422, a second communication module 424, a processor 426, and a memory 428. However, the second electronic device 420 shown in FIG. 4B is just one embodiment of the present disclosure and may have several modifications on the basis of the components shown in FIG. 4B. For example, the second electronic device 420 may further include a user interface such as a keyboard and a mouse or a sensor for receiving instructions or information from a user.

The first communication module 422 or the second communication module 424, for example, may include at least the same or similar configuration to the communication interface 170 shown in FIG. 1.

The first communication module 422 may perform cellular communication and/or data communication. For example, the first communication module 422 may include a circuit switching module 4220 (a “CS” module) for performing the cellular communication and a packet switching module 4225 (a “PS” module) for performing the data communication.

The second communication module 424 may perform a communication to connect the second electronic device 420 with the first electronic device 410. The communication, for example, may be a short range communication including at least one of BT, ZigBee, NFC, WiFi direct, and radio frequency identification (RFID).

Hereinafter, the case that the second communication module 424 is connected to (e.g., paired with) the first electronic device 410 by using BT will be described as an example. Since the BT is limited in terms of distance, when the first electronic device 410 and the second electronic device 420 are distanced more than a predetermined (or threshold) distance from each other, the pairing may be broken or otherwise released. Additionally, even when the first electronic device 410 and the second electronic device 420 are within the predetermined distance, the pairing may be released according to a network state or interference from a building or structure.

The processor 426, for example, may include at least the same or similar configuration to the processor 120 shown in FIG. 1.

The processor 426 may generate a signal for requesting call forwarding on the basis of (or in response to detecting) a specified condition. Additionally, the processor 426 may transmit the generated signal for requesting call forwarding to the carrier 440 by using the first communication module 422. However, as described above, the generated signal for requesting call forwarding may be directly transmitted from the second electronic device 420 to the carrier 440 but according to various embodiments of the present disclosure, the generated signal for requesting call forwarding may be transmitted to the carrier 440 through the first electronic device 410. Further, the generated signal for requesting call forwarding may be directly transmitted from the second electronic device 420 to the first electronic device 410 but may be transmitted to the first electronic device 410 through the electronic device management sever 430.

A specified condition for generating the signal for requesting call forwarding, for example, may include the case in which pairing with the first electronic device 410 is released (e.g., communication is terminated or broken). One example may include the situation where two devices are separated by more than predetermined distance spaced from each other because a user leaves the first electronic device 410 in the home and leaves the home with only the second electronic device 420.

Additionally, the specified condition may include the case where the second electronic device 420 is connected to the electronic device management sever 430 through the first communication module 422. According to various embodiments of the present disclosure, when the pairing with the first electronic device 410 is released, the second electronic device 420 may be connected to the electronic device management server 430. However, as soon as the pairing with the first electronic device 410 is released, the second electronic device 420 may not be connected to the electronic device management sever 430 (e.g., disconnected) and when the pairing release is maintained for a specified time, the second electronic device 420 may be connected to the electronic device management server 430. For example, call forwarding may be unnecessary when a user leaves the first electronic device 410 in a room and goes to a living room for a short time with only the second electronic device 420. Additionally, even when the first electronic device 410 and the second electronic device 420 are close to each other, if a network environment is temporarily poor, pairing may be released. In this case, since it is possible that the network environment will be quickly restored and pairing restored, according to various embodiments of the present disclosure, if the pairing is not restored for a specified time after the pairing is released, the call forwarding may be established.

According to various embodiments, the specified condition may include a case of receiving a user input for generating a signal for requesting the call forwarding through a call forwarding UI.

As the above-mentioned condition, the call forwarding UI may be displayed on a screen of the second electronic device 420 when the pairing with the first electronic device 410 is released, or when the second electronic device 420 is connected to the electronic device management server 430. In this case, when a user wants call forwarding, the call forwarding may be established by receiving a user input. Accordingly, automatic call forwarding may be prevented when a user does not want call forwarding, for example, when a network state is not good for a time period, or when the first electronic device 410 and the second electronic device 420 are separated from each other for only a brief moment. Additionally, the call forwarding UI may be displayed on the screen of the second electronic device 420 through a user input for calling the call forwarding UI. That is, when a user wants to use call forwarding in addition to the case that the pairing with the first electronic device 410 is released or the case that the second electronic device 420 is connected to the electronic device management sever 430, the second electronic device 420 may allow a user to select whether to made the call forwarding by displaying the call forwarding UI.

When the pairing between the second electronic device 420 and the first electronic device 410 is released or when the second electronic device 420 is connected to the electronic device management server 430, a user may set not to use call forwarding in the call forwarding UI. When pairing is released (disconnected), a user may use the second electronic device 420 without call forwarding. When call forwarding is desired, a user may use the call forwarding service by displaying the call forwarding UI on the screen of the second electronic device 420 through a user input.

When the call forwarding service is utilized, instead of the first electronic device 410, the first communication module 422 may receive a voice call signal or message that targets the first electronic device 410 as a reception device from the carrier 440.

The second electronic device 420 may further include a sensor (e.g., as part of the sensor module 240) for detecting a human body. The processor 426 may activate the first communication module 422 or may generate a signal for requesting call forwarding only when a human body is detected. For example, the reason is that when a user carries out only the first electronic device 410 instead of the second electronic device 420, call forwarding is not supposed to be made.

However, according to various embodiments of the present disclosure, even when the human body (user) is detected, whether to make call forwarding may be adaptively determined according to a wearing state of the second electronic device 420. For example, the processor 426 may not perform call forwarding when a user exercising or sleeping while wearing the second electronic device 420.

The first communication module 422 of the second electronic device 420 may be in an activated state at all times. However, according to various embodiments of the present disclosure, the first communication module 422 may be in a deactivated state in order to allow for low power consumption. In this case, the first communication module 422 may be activated in order for performing the above-mentioned call forwarding. An activation operation of the first communication module 422 may be performed similar to a generation operation of a signal requesting call forwarding.

For example, when a connection with the first electronic device 410 is terminated (e.g., by disconnection), or when the second electronic device 420 is connected to the electronic device management server 430 through the first communication module 422, or when a user input requesting the activation of the first communication module 422 is received through a first communication module activation UI, the processor 426 may activate the first communication module 422.

However, according to various embodiments of the present disclosure, the call forwarding request and the activation of the first communication module 422 correspond to each other and they may be performed simultaneously.

As mentioned above, the first communication module 422 may include the CS module 4220 and the PS module 4225, and an operation for activating the first communication module 422 may including activating at least one of the CS module 4220 and the PS module 4225. For example, the processor 426 may activate both the CS module 4220 and the PS module 4225. However, according to various embodiments of the present disclosure, the processor 426 may also activate only the CS module 4220. If the CS module 4220 is in an activated state already, an operation for activating the first communication module 422 may be an operation for activating the PS module 4225.

The processor 426 may generate a signal for requesting the release of call forwarding in order to transmit a voice call signal or message to the first electronic device 410. During the call forwarding service, a user cannot directly make a call or transmit a message to the first electronic device 410. Accordingly, in order to directly make a call or transmit a message to the first electronic device 410, the call forwarding service needs to be released, so a user may call the call forwarding UI and may generate a signal for requesting release of call forwarding, based on a user input for requesting release of call forwarding. The generated signal for requesting release of call forwarding may be transmitted to the carrier 440 through the first communication module 422. According to various embodiments of the present disclosure, the generated signal for requesting release of call forwarding may be directly transmitted to the carrier 440 or may be transmitted to the carrier 440 through the first electronic device 410 (or through the electronic device management sever 430).

Additionally, a release operation for the call forwarding service may be performed in a procedure which is essentially the reverse of an operation for starting the call forwarding service. For example, during the use of call forwarding service, when the second electronic device 420 is connected to the first electronic device 410 or when a connection with the electronic device management server 430 is disconnected, the call forwarding service may be released.

A signal for requesting call forwarding or a signal requesting the release of call forwarding may be in one format of a voice message, a text message, a multimedia message, a Mobile Application Part (MAP) message, and an Unstructured Supplementary Service Data (USSD) message.

During the utilization of the call forwarding service, the processor 426 may display an indicator notifying a user that the call forwarding service is active on a screen. Similarly, while the first communication module 422 activated, the processor 426 may display an indicator for notifying that the first communication module 422 is in activation on the screen.

The memory 428 may store data. The memory 428, for example, may include at least the same or similar configuration to the memory 130 shown in FIG. 1. At this point, the data stored in the memory 428 may include data inputted and outputted between each component inside the second electronic device 420 and may include data inputted and outputted between the second electronic device 420 and components outside the second electronic device 420. For example, the memory 428 may store information on the first electronic device 410, which is received by the second communication module 424. An embodiment of such the memory 428 may include hard disk drive, ROM, RAM, flash memory, and a memory card inside or outside the second electronic device 420.

The content mentioned with reference to FIG. 4B may be applied to the above-mentioned multi-SIM concept as another embodiment of the present disclosure. For example, in addition to the case that the pairing between the second electronic device 420 and the first electronic device 410 is released, when the second electronic device 420 is connected to the electronic device management server 430 and a user input for generating a signal for requesting the call forwarding is received through a call forwarding UI, the sub-SIM property assigned to the second electronic device 420 may change into the main-SIM property by the carrier 440.

When the call forwarding is released, it may be similarly applied. For example, during the use of call forwarding service, when pairing with the first electronic device 410 is present, or when the connection with the electronic device management server 430 is disconnected, or when a user input for generating a signal for requesting the release of the call forwarding service is received, the main-SIM property assigned to the second electronic device 420 may change into the sub-SIM property by the carrier 440.

Those skilled in the art understand enough that the first communication module 422, the second communication module 424, the processor 426, and the memory 428 may be separated and implemented or at least one of them is integrated and implemented.

FIG. 4C is a block diagram of the first electronic device 410 according to various embodiments of the present disclosure. Referring to FIG. 4C, the first electronic device 410 may include a first communication module 412, a second communication module 414, a processor 416, and a memory 418. However, the first electronic device 410 shown in FIG. 4C is just one embodiment of the present disclosure and several modifications on the basis of the components shown in FIG. 4C are possible identical to those of FIG. 4C.

The first communication module 412 or the second communication module 414, for example, may include at least the same or similar configuration to the communication interface 170 shown in FIG. 1.

The first communication module 412 may perform cellular communication and data communication. Additionally, the second communication module 414 may perform a communication to connect to the second electronic device 420. As mentioned with reference to FIG. 4B, the first electronic device 410 and the second electronic device 420 are paired mutually by using a short range communication such as BT.

According to various embodiments of the present disclosure, while a connection between the first electronic device 410 and the second electronic device 420 is maintained, the first communication module 412 may receive a voice call signal or a message that directed to the first electronic device 410 as a reception device from the carrier 440. However, even while a connection between the first electronic device 410 and the second electronic device 420 is maintained, if a call forwarding service using the second electronic device 420 as a target device is in use, a voice call signal or message using the first electronic device 410 as a reception device may be received by the second electronic device 420.

The processor 416, for example, may include at least the same or similar configuration to the processor 120 shown in FIG. 1.

The processor 416 may generate a signal for requesting call forwarding when a connection between the first electronic device 410 and the second electronic device 420 is terminated or disconnected. The processor 416 may transmit the generated signal for requesting call forwarding to the carrier 440 using the first communication module 412. Alternatively, when receiving the signal requesting call forwarding from the second electronic device 420 or the electronic device management server 430 through the first communication module 412, the processor 416 may transmit the received signal requesting call forwarding to the carrier 440 using the first communication module 412. According to various embodiments of the present disclosure, the processor 416 may generate a new message requesting call forwarding on the basis of the received signal for requesting call forwarding, and may transmit the newly generated message to the carrier 440 through the first communication module 412.

When the first electronic device 410 and the second electronic device 420 are connected again through the second communication module 414, the processor 416 may generate a signal for requesting release of call forwarding. The processor 416 may transmit the generated signal for requesting release of call forwarding to the carrier 440 through the first communication module 412.

Alternatively, when receiving, from the electronic device management sever 430, a communication-disabled state notification on the second electronic device 420 through the first communication module 412, the processor 416 may generate a signal for requesting the release of call forwarding, and transmit it to the carrier 440 through the first communication module 412.

During the use of call forwarding service, the processor 416 may display an indicator for notifying that the call forwarding service is in use on a screen of the first electronic device 410. Accordingly, a user may check whether call forwarding service is in use by checking the indicator displayed on the screen of the first electronic device 410. If a user leaves the second electronic device 420 in the home and carries only the first electronic device 410, a connection between the first electronic device 410 and the second electronic device 420 is disconnected, and thus, a call forwarding service may be established. In this case, since a user cannot receive any contact with only the first electronic device 410, the user may notice the indicator on the screen, and apply a user input to allow the processor 416 to display a call forwarding UI controlling the call forwarding service.

According to various embodiments of the present disclosure, when a connection between the first electronic device 410 and the second electronic device 420 is disconnected, the processor 416 may display the call forwarding UI on the screen without an additional user input in order to query a user as to whether to use a call forwarding service.

In addition to the case where a connection between the first electronic device 410 and the second electronic device 420 is terminated or disconnected, when the first electronic device 410 is connected to the electronic device management sever 430 or receives a user input for requesting the call forwarding on the call forwarding UI, the call forwarding service may be performed through a user input for requesting call forwarding. Accordingly, the operation mentioned for call forwarding service in the case that a connection between the first electronic device 410 and the second electronic device 420 is disconnected may be applied to the case that the first electronic device 410 is connected to the electronic device management sever 430 or receives the user input for requesting the call forwarding.

On the other hand, an operation for releasing call forwarding may be performed when the first electronic device 410 and the second electronic device 420 are connected to each other, when a connection between the first electronic device 410 and the electronic device management server 430 is disconnected, or when there is a user input for requesting the release of call forwarding.

The memory 418 may store data. The memory 418, for example, may include at least the same or similar configuration to the memory 130 shown in FIG. 1. At this point, the data stored in the memory 418 includes data inputted and outputted between each component inside the first electronic device 410 and may include data inputted and outputted between the first electronic device 410 and components outside the first electronic device 410.

Those skilled in the art would understand that the first communication module 412, the second communication module 414, the processor 416, and the memory 418 may be implemented separately, or at least one of them is implemented integrally.

Hereinafter, various operations performed in the first electronic device 410 and the second electronic device 420 will be described in more detail.

FIGS. 5A to 5C are flowcharts illustrating a call forwarding method when a pairing between the first electronic device 410 and the second electronic device 420 is released according to various embodiments of the present disclosure. The call forwarding method based on the pairing release according to an embodiment shown in FIGS. 5A to 5C may include operations processed in time series in the first electronic device 410, the second electronic device 420, the electronic device management server 430, the carrier 440, and the network 450 according to the various embodiments shown in FIGS. 1 to 4. Accordingly, even if there are contents omitted below, the contents described in relation to the first electronic device 410, the second electronic device 420, the electronic device management server 430, the carrier 440, and the network 450 of FIGS. 1 to 4 may be applied to the call forwarding method based on the pairing release according to the embodiments shown in FIGS. 5A to 5C.

Referring to FIG. 5A, a pairing between the first electronic device 410 and the second electronic device 420 may be released (disconnected) in operation 502. Basically, an effective distance of a pairing using BT may be within 10 meters and the pairing may be released as it is out of the effective distance. Besides that, the release of the pairing may be made by turning off one of the first electronic device 410 and the second electronic device 420 or a user input of a user who releases the pairing.

In operation 504, the second electronic device 420 may detect the pairing release in operation 502 and may activate a communication function. For example, the second electronic device 420 may activate only a communication function (for example, the second communication module 424) utilized for the pairing during the pairing and may activate a cellular communication function and a data communication function (the first communication module 422) when the pairing is released. According to various embodiments of the present disclosure, the second electronic device 420 may activate any one function of the CS module 4220 and the PS module 4225.

According to another embodiment of the present disclosure, a communication function of the second electronic device 420 may be in an activated state at all times. However, this may accelerate the battery consumption of a wearable device (for example, the second electronic device 420) and as mentioned above, the second electronic device 420 may activate only a communication function utilized for the pairing.

In operation 506, the second electronic device 420 may generate a signal for requesting call forwarding and transmit it to the carrier 440. The signal may be formed of any one format among a voice message, a text message, a multimedia message, an Unstructured Supplementary Service Data (USSD) message, and a Mobile Application Part (MAP) message.

In operation 508, the carrier 440 may start call forwarding service to transmit a call and/or message received from external by targeting the first electronic device 410 as a reception device, to the second electronic device 420 in response to the call forwarding request signal received in operation 506.

Referring to FIG. 5B, a pairing between the first electronic device 410 and the second electronic device 420 may be released (disconnected) in operation 512 and on the basis of this, the second electronic device 420 may activate a communication function in operation 514.

In operation 516, the second electronic device 420 may generate a signal for requesting call forwarding and may transmit the generated signal requesting call forwarding to the first electronic device 410 using the communication function activated in operation 514.

In operation 518, the first electronic device 410 may transmit the signal for requesting call forwarding received in operation 516 to the carrier 440.

In operation 520, the carrier 440 may initiate the call forwarding service to forward a call and/or message directed to the first electronic device 410 (e.g., as a reception device) to the second electronic device 420, in response to the call forwarding request signal received in operation 518.

Referring to FIG. 5C, the first electronic device 410 and the second electronic device 420 may be paired with each other in operation 522.

In operation 524, the first electronic device 410 and the second electronic device 420 may mutually exchange information during pairing. For example, the first electronic device 410 may obtain identification information on the second electronic device 420 and the second electronic device 420 may obtain identification information on the first electronic device 410.

In operation 526, the pairing between the first electronic device 410 and the second electronic device 420 may be released due to various causes. For example, when a communication state degrades or becomes worse, or a distance between the first electronic device 410 and the second electronic device 420 grows to be more than an effective distance of communication, pairing may be released.

In operation 528, the second electronic device 420 may activate a communication function on the basis of the pairing release in operation 526.

In operation 530, the second electronic device 420 may request a connection from the electronic device management server 430. Similarly, in operation 531, the first electronic device 410 may request a connection from the electronic device management server 430. The order of operation 530 and operation 531 may be changed or may be performed at the same time. In some alternate embodiments, only one of operation 530 and operation 531 may be performed.

In operation 532, the electronic device management server 430 may establish a communication session between the first electronic device 410 and the second electronic device 420. For example, the connection request received in operation 530 may include information on the first electronic device 410 and the second electronic device 420, and the electronic device management server 430 may establish the session between the first electronic device 410 and the second electronic device 420 by using the information on the first electronic device 410 and the second electronic device 420. Similarly, the connection request received in operation 531 may include information on the first electronic device 410 and the second electronic device 420, and the electronic device management server 430 may establish the session between the first electronic device 420 and the second electronic device 420 using the information on the first electronic device 410 and the second electronic device 420.

Through the established session, the first electronic device 410 and the second electronic device 420 may mutually transmit and/or receive data. In operation 534 and operation 536, the second electronic device 420 may transmit a signal for requesting call forwarding to the first electronic device 410 through the electronic device management server 430.

In operation 538, the first electronic device 410 may transmit the signal for requesting call forwarding received in operation 536 to the carrier 440. According to various embodiments of the present disclosure, the first electronic device 410 may generate the signal for requesting call forwarding to transmit it to the carrier 440 on the basis of only operation 532 without operation 534 and operation 536.

In operation 540, the carrier 440 may start call forwarding service to transmit a call and/or message directed to the first electronic device 410 (e.g., as a reception device) to the second electronic device 420 in response to the call forwarding request signal received in operation 538.

FIG. 5D is a flowchart illustrating a communication method with the first electronic device 410 and the second electronic device 420 during call forwarding release according to various embodiments of the present disclosure.

In operation 542, the carrier 440 may transmit to the second electronic device 420 a call and/or message directed to the first electronic device 410 (e.g., as a reception device) based on the established call forwarding performed in operation 508, operation 520, or operation 540.

However, when call forwarding to the second electronic device 420 is operative, a user cannot send a call or transmit a message to the first electronic device 410 using the second electronic device 420, which may be required, such as when the first electronic device 410 is given to children to prevent an emergency situation, or if, after leaving the first electronic device 410 in a certain place, the user tries to contact someone who is near the first electronic device 410 at the certain place. Accordingly, a user carrying the second electronic device 420 may need to release (by using the second electronic device 420) a call forwarding service sets the second electronic device 420 as a target device.

In operation 544, the second electronic device 420 may transmit to the carrier 440 a release request for the call forwarding service setting the second electronic device 420 as a target device. In this case, a signal for requesting a call forwarding release, as described above, may be formed of any one format among a voice message, a text message, a multimedia message, an USSD message, and a MAP message.

According to various embodiments of the present disclosure, the second electronic device 420 may transmit to the carrier 440 the release request for the call forwarding service through the first electronic device 410. Alternately, the second electronic device 420 may transmit to the carrier 440 the release request for the call forwarding service through the electronic device management server 430 and the first electronic device 410.

In operation 546, the carrier 440 may release the call forwarding service setting the second electronic device 420 as a target device based on a call forwarding release request message received in operation 544.

In operation 548, the carrier 440 may transmit to the first electronic device 410 call and/or message directed to the first electronic device 410 (e.g., as a reception device), which is transmitted to the second electronic device 420 instead of the first electronic device 410 due to the provisions of the established call forwarding service.

In operation 550, the second electronic device 420 may transmit to the carrier 440 a call or message to be sent to the first electronic device 410.

In operation 552, the carrier 440 may transmit the call or message received in operation 550 to the first electronic device 410 based on the released call forwarding service performed in operation 546.

The order of operation 502 to operation 552 described with reference to FIGS. 5A to 5D is just an example and the disclosure is not limited thereto. That is, the order of the above-mentioned operations may mutually vary according to time, and some operations among them may even be performed at the same time (e.g., simultaneously). Additionally, the above-mentioned operations may be repeated periodically at specified times and/or may be performed again on the basis of a user input inputted from a user.

Furthermore, since some operations may be omitted, for example, a not-received (e.g., missed) call and/or message to be transmitted to the first electronic device 410 in operation 548 may not be transmitted in addition to the transmitted information.

FIG. 6 is a flowchart illustrating a method of managing the electronic device management device 430 in correspondence to the case that a communication of the first electronic device 410 is disabled during the call forwarding service according to various embodiments of the present disclosure. The management method of the electronic device management device 430 during the communication disability of the first electronic device 410, according to an embodiment shown in FIG. 6, may include operations processed in time series in the first electronic device 410, the second electronic device 420, the electronic device management server 430, the carrier 440, and the network 450 according to the various embodiments shown in FIGS. 1 to 4. Accordingly, even if there are contents omitted below, the contents described in relation to the first electronic device 410, the second electronic device 420, the electronic device management server 430, the carrier 440, and the network 450 of FIGS. 1 to 4 may be applied to the management method of the electronic device management device 430 during the communication disability of the first electronic device 410 according to an embodiment shown in FIG. 6.

In operation 602, the electronic device management server 430 may check a communication state of the first electronic device 410. The checking of the communication state performed in operation 602 may be performed periodically by a specified time unit and this may be performed by using a network ping.

In operation 604 and operation 606, when a communication-disabled state of the first electronic device 410 occurs, the electronic device management server 430 may check whether the communication disabled state of the first electronic device 410 continues for a specified time.

In operation 608, when the communication disabled state of the first electronic device 410 continues for the specified time, the electronic device management server 430 may notify the second electronic device 420 that the first electronic device 410 is in the communication disabled state.

According to another embodiment of the present disclosure, operation 606 may be omitted and in this case, as soon as it is checked that the first electronic device 410 is in the communication disabled state, the electronic device management server 430 may notify the second electronic device 420 that the first electronic device 410 is in the communication-disabled state.

The order of operation 602 to operation 608 described with reference to FIG. 6 is just an example and the disclosure is not limited thereto. That is, the order of the above-mentioned operations may mutually vary and some operations among them may be performed at the same time. Additionally, the above-mentioned operations may be repeated periodically at specified times and may be performed again on the basis of a user input.

FIGS. 7A and 7B are flowcharts illustrating a method of managing the electronic device management device 430 in correspondence to the case that a communication of the second electronic device 420 is disabled during call forwarding service according to various embodiments of the present disclosure. The management method of the electronic device management device 430 during the communication disability of the second electronic device 420 according to an embodiment shown in FIGS. 7A and 7B may include operations processed in time series in the first electronic device 410, the second electronic device 420, the electronic device management server 430, the carrier 440, and the network 450 according to the various embodiments shown in FIGS. 1 to 4. Accordingly, even if there are contents omitted below, the contents described in relation to the first electronic device 410, the second electronic device 420, the electronic device management server 430, the carrier 440, and the network 450 of FIGS. 1 to 4 may be applied to the management method of the electronic device management device 430 during the communication disability of the second electronic device 420 according to an embodiment shown in FIGS. 7A and 7B.

Referring to FIG. 7A, in operation 702, the electronic device management server 430 may check (or detect) a communication state of the second electronic device 420. The checking of the communication state performed in operation 702 may be performed periodically by using a network ping.

In operation 704 and operation 706, when a communication disabled state of the second electronic device 420 occurs, the electronic device management server 430 may check whether the communication disabled state of the second electronic device 420 continues for a specified time.

In operation 708, when the communication disabled state of the first electronic device 420 continues for the specified time, the electronic device management server 430 may notify the first electronic device 410 that the second electronic device 420 is in the communication disabled state.

In operation 710, the first electronic device 410 may transmit to carrier 440 a release request for the call forwarding service set the second electronic device 420 as a target device.

In operation 712, the carrier 440 may release a call forwarding service set for the second electronic device 420 in response to the call forwarding release request received in operation 710.

Operation 714 illustrates that a call or message targeted to the first electronic device 410 is transmitted to the first electronic device 410 according to the release of the call forwarding service.

In operation 716 and operation 718, when the communication disabled state of the second electronic device 420 is eliminated, the second electronic device 420 may transmit to carrier 440 a call forwarding service request.

According to another embodiment of the present disclosure, the elimination of the communication disabled state of the second electronic device 420 shown in operation 716 may be obtained by checking a communication state check performed periodically in the electronic device management server 430. Accordingly, the electronic device management server 430 may request a call forwarding service for the second electronic device 420 from the carrier 440.

In operation 720, the carrier 440 may transmit, to the second electronic device 420, information on a call or message transmitted to the first electronic device 410 in operation 714.

In this case, the carrier 440 may transmit the not-received (e.g., missed) message as it is to the second electronic device 420. In one alternative, the carrier 440 may transmit the not-received message in summary form to the second electronic device 420 and, only when it receives a request of details from the second electronic device 420, the carrier 440 may transmit an original message to the second electronic device 420.

In another embodiment, the second electronic device 420 may receive a not-received or missed message in an original form from the carrier 440, but may display the received missed message in a summary form on a screen.

Here, the message in summary form may represent the number of the not-received messages. The original message may represent the caller, calling time, and message content of a not-received message. Information on the not-received call may include the caller and calling time of the not-received call.

Additionally, a subject for transmitting a not-received call or message to the second electronic device 420 in operation 718 may be the electronic device management server 430 instead of the carrier 440.

Hereinafter, FIG. 7B illustrating a different embodiment from FIG. 7A will be described. Operation 702 to operation 718 shown in FIG. 7B correspond to operation 702 to operation 718 shown in FIG. 7A and the same operation numbers are assigned. Accordingly, descriptions of overlapping contents are omitted.

Referring to FIG. 7B, in operation 722, the electronic device management server 430 may check a communication state of the second electronic device 420. The communication state check performed in operation 722 may be identical to the communication state check performed in operation 706.

In operation 724, the electronic device management server 430 may transmit to the first electronic device 410 a state in which a communication of the second electronic device 420 is available.

In operation 726 and operation 728, the first electronic device 410 may transmit information on the call or message transmitted to the first electronic device 410 in operation 714 to the second electronic device 420 through the electronic device management server 430.

According to various embodiments of the present disclosure, the electronic device management server 430 may synchronize a call, message, and event history delivered to each electronic device regardless of a call forwarding setting (e.g., enabled or disabled) in the carrier 440. Accordingly, in this case, operation 724 and operation 726 may be omitted, and when the second electronic device 420 enters a communicable state through operation 722 from the communication disability state, the electronic device management server 430 may directly transmit information for the not-received call and/or the not-received message (e.g., missed calls and/or messages) to the second electronic device 420.

The order of operation 702 to operation 728 described with reference to FIGS. 7A and 7B is just an example and the disclosure is not limited thereto. That is, the order of the above-mentioned operations may mutually vary and some operations among them may be performed at the same time. Additionally, the above-mentioned operations may be repeated periodically at each specified time and may be performed again on the basis of a user input.

FIG. 8 is a flowchart illustrating a communication function activation method of the second electronic device 420 according to various embodiments of the present disclosure. The communication function activation method of the second electronic device 420 according to an embodiment shown in FIG. 8 may include operations processed in a time series in the first electronic device 410, the second electronic device 420, the electronic device management server 430, the carrier 440, and the network 450 according to the various embodiments shown in FIGS. 1 to 7. Accordingly, even if there are contents omitted below, the contents described in relation to the first electronic device 420, the second electronic device 420, the electronic device management server 430, the carrier 440, and the network 450 of FIGS. 1 to 7 may be applied to the communication function activation method of the second electronic device 420 according to an embodiment shown in FIG. 8.

In operation 810, the second electronic device 420 may be paired with the first electronic device 410 through a BT network.

In operation 820, a BT pairing that mutually matches the second electronic device 420 and the first electronic device 410 may be released due to various causes. The release of the BT pairing will be described with the next example.

According to operation 822, a distance between the second electronic device 420 and a smartphone may become greater than a BT communicable distance. For example, when a user leaves the first electronic device 410 in a room and goes to a bathroom, the BT pairing between the second electronic device 420 and the first electronic device 410 may be released due to the distance created. According to operation 824, when power of the second electronic device 420 is switched off (e.g., by a user input turning off power, or battery exhaustion or depletion), the BT pairing between the second electronic device 420 and the first electronic device 410 may be released. According to operation 826, the BT pairing between the second electronic device 420 and the first electronic device 410 may be released by a user input directed releasing of the BT pairing.

In operation 830, the second electronic device 420 may display a communication module activation UI 835 on a screen for whether to activate the first communication module 422.

In operation 840, the second electronic device 420 may perform a predetermined operation by a user input through the communication module activation UI 835 or the satisfaction of a specified condition.

For example, according to operation 842 or operation 844, when the second electronic device 420 does not receive a selection input for a specified time, or receives a user input for activating the first communication module 422, as shown in operation 852, the second electronic device 420 may activate the first communication module 422.

On the other hand, according to operation 846, when the second electronic device 420 receives a user input for not activating the first communication module 422, as shown in operation 856, the second electronic device 420 may maintain the first communication module 422 to be in an inactivated state.

FIG. 9 is a flowchart illustrating a call forwarding service activation method according to various embodiments of the present disclosure. The call forwarding service activation method to the second electronic device 420 according to an embodiment shown in FIG. 9 may include operations processed in time series in the first electronic device 410, the second electronic device 420, the electronic device management server 430, the carrier 440, and the network 450 according to the various embodiments shown in FIGS. 1 to 8. Accordingly, even if there are contents omitted below, the contents described in relation to the first electronic device 420, the second electronic device 420, the electronic device management server 430, the carrier 440, and the network 450 of FIGS. 1 to 8 may be applied to the call forwarding service activation method according to an embodiment shown in FIG. 9.

In operation 910, the second electronic device 420 may be paired with the first electronic device 410 through a BT network.

When a BT pairing mutually matching the second electronic device 420 and the first electronic device 410 is released in operation 922, the second electronic device 420 may display a call forwarding UI 935 (e.g., a user interface) on a screen for asking whether to use call forwarding service in operation 930.

Alternatively, when the second electronic device 420 is connected to the electronic device management server 430 in operation 924 after the BT pairing between the second electronic device 420 and the first electronic device 410 is released, the second electronic device 420 may display the call forwarding UI 935 in operation 930.

Alternatively, when receiving a user input for calling the call forwarding UI 935 in operation 926, the second electronic device 420 may display the call forwarding UI 935 in operation 930.

According to operation 942 or operation 944, when the second electronic device 420 does not receive an input for the call forwarding UI 935 for a specified time, or receives a user input for using call forwarding service, the second electronic device 420 may use the call forwarding service in operation 952.

On the other hand, according to operation 946, when the second electronic device 420 receives a user input for not using the call forwarding service, the second electronic device 420 may not use the call forwarding service in operation 956.

Hereinafter, with reference to FIGS. 10 and 11, according to a communication module activation or a call forwarding service use, an indicator displayed on each screen of the first electronic device 410 and the second electronic device 420 will be described.

FIG. 10 is a view illustrating an indicator displayed on each screen of the first electronic device 410 and the second electronic device 420 according to various embodiments of the present disclosure.

Referring to FIG. 10, the reference number 1010 represents the second electronic device 420 when the first communication module 422 is not activated and the reference number 1020 represents the second electronic device 420 when the first communication module 422 is activated.

When comparing the reference number 1010 and the reference number 1020, while the first communication module 422 of the second electronic device 420 is activated, a communication indicator 1025 indicating that the first communication module 422 is in an activated state may be displayed on the screen of the second electronic device 420. However, in this case, the “3G” indicator shown in the communication indicator 1025 is a mere example of a cellular communication mode used in the first communication module 422, and it is understood that various embodiments of the present disclosure are not limited to using only 3G as a cellular communication. The second electronic device 420 may use various communication functions, such as LTE or LTE-A. Additionally, the first communication module 422 uses the CS module 4220 and also the PS module 4225 and when data communication is used, an indicator for a corresponding communication may be displayed on the screen.
